Investigation of the plasma inhomogeneities in a plasma opening switch by laser methods

Abstract

This paper is devoted to the investigation of turbulent noises in the plasma of a pulsed power plasma opening switch (POS). A diagnostic system based on a schlieren-image scheme was developed and applied at the 140 kA "Taina" facility. Using a YAG:Nd laser allows to detect plasma noises by laser beam scattering effect. Preliminary data analysis gives range… (More)
